Patented July 5, 1932 UNITED STATES PATENT OFFICE ALFRED G. F KUROWSKI,F BROOKLYN, NEW YORK, ASSIGNOR T0 UNDERWOOD EL- LIOTT FISHER COMPANY, OFNEW YORK, N. Y., A. CORPORATION OF DELAWARE TYIPEWRITING MACHINECARRYING CASE Original application filed April 24, 1924, Serial No.708,633. Divided and this application filed August 6,

i 1927. Serial No. 211,078.

This invention relates to improvements in typewriting machine carryingcases, and particularly to types commonly known as portables, in whichthe machine is normally en- 7 6 closed within a case adapted to beconveniently carried by hand.

One of the objects of the invention is .to provide a two-part, separablecase in which 6 the cover element maybe positively and safe- .1y securedto the base'in such manner as to efl'iciently protect the machine fromintrusion, damage, dust or'moisture, under ordinary conditions oftransit or storage, or to permit the ready removal of the cover to allowauthorized use of the machine, either as aflixed to the base element ofthe case or removed operably intact therefrom.

Another purpose is. to produce a carrying case base provided with meanswhich operate effectually in minimizing, reducing and preventing thetransmission of sound, incurred by operation of the machine, absorbingaircarried sound vibrations to a marked degree. A further feature is theconstruction of a carrying case having its top, two sides and base-plateformed of sheet-metal for obtaining a casing of minimum height and widthwith respect to the typewriting machine.

A further aim is in the provision of an unusually light, strong'andcompact carrying case of pleasing design, readily portable and having abase-wall suited as a support upon which the machine may be convenientlyoperated, while acting as a silencer for any sound produced. r

This application is a division of my application, Serial No. 708,633,filed April 24, 1924. r Other features and advantages will here-'inafter appear. i

' warranted intrusion.

Figure 3 is a fragmentary sectional view taken on line 33 of Figure 2.

Figure 4 is a similar view taken on line l4: of Figure 2.

The portable typewriter, shown in broken lines in Figure l anddesignated generallyby the numeral 10, is standard in all respects andconstitutes a complete commercial entity.

The carrying case is composed of a front end plate or member 15,preferably made of well-seasoned wood, as is also the rear end plate ormember 16. An integral piece of sheet-metal is formed to present sidewalls 17 and. a cover 18, inclined downwardly at the front 19 and havinginwardly-curved edges 18 engaged in corresponding recesses in the upperand end edges of theplates l5 and 16, to which the cover-plate isrigidly secured, and the entire outer surface of the casing isinsheathed in leather.

A strap handle 20 is provided on the front end plate 15 forconveniencein carrying, and

a lock, generally designated by the numeral 21, is furnished to providesecurity from un- Fixed near each of the four corners of the bottomplate are button-headed nails 22 or the like to protect theleather-covered surface of the case, when resting on its bottom or lowerend, the foregoing elements constituting the cover or removable portionof the case.

The base-portion is composed ofa wooden frame 23 formed fromquarter-roundmolding with mitered joints, freely receivable within thelower portion of the cover.

A sheet-metal plate 24: is secured to the flat lower surface of theframe 23, and is provided on its lower exposed side with a leathercovering, from which extend four cushioning elements, as the rubber feet25, held in rigid engagement by cement or like adhesive.

The rear, member of the frame 23 contains recesses 26 adjacent its ends,these recesses having metallic-linings 27 suited to be e11- gaged by apair of hooks 28, fixed to the inner surface of the rear end plate 16,and adapted. to interlock with the linings to removably engage the rearend of the base within the cover, as best shown in Figure 3.

Set midway in the length of the front member of the frame 23 is abutton-headed stud 29 projecting to interlock with a spring-latchincorporated in the lock 21, see Figure 1, thus co-operating with thehooks 28 at the opposite end to securely lock the cover to the base,constituting a single carrying unit.

The typewriting machine 10, as indicated by broken lines in Figure 1, ascomposed of a pair of east side frames 11 having extending base-pads 12,serving as feet during assembly of the machine, the same being drilledand tapped, to receive detachable rubber feet The typewriter-frame sides11 terminate,

'as shown in Figure 1, at the inner row of the key-levers to define amachine-base area, but

affording no protection to the bank of keys,

as it would obviously add greatly to the weightof the frame andcasing ifit were continued-around the keyboard in the usual manner.

The frame 11 is enclosed by a highly-polishedouter frame or silencingpocket shaped by power press methods from a single piece of sheet-metalto produce opposed side walls 30 and rear wall 31, all of which haveinwardly-curved or rounded-over upper edges 30 and 31' resentin a smoothand a reeporous felt 39, the same acting to absorb soundemanations,which would otherwise be transmitted 'to the supporting base.

The upper surfaces ofthe ledge 33, crossbar34 andentire base-plate35 aresimilarly covered with a like but thinner felt fabric 40, and thus,when-the machine is set in the en- "closing frame, its feet rest uponthe lined surface 40.

In order to secure the feet 41 to the base of the carrying case andprevent any relative shifting movement, flanged metallic rings 45 arefixedin appropriate locations in the base, these rings being receptiveof the feet and which are positively but removably held therein by thefollowing means.

' Extending oppositely outward from the sides-3O of the outer frame arerigid studs 46 having rounded outer ends, these studs being suited toengage in openings formed through latch-elements 47, pivotally supportedin brackets 48, fixed on the base-plate 24, as bestseen in- Figure 4.

The outer ends of the latches are curved to provide finger-holds andtheir inner ends project beyond their pivotal points to engage the freeend of a spring-detent 49 riveted to the plate 24 and extending belowthe pivot in the bracket 48, the detent being so shaped and arranged asto hold the latch 47 in either a raised, operatively engaging, positionor when turned down to clear the studs 46.

These latches are readily accessible when the cover of the carrying caseis removed and are operable by hand only, no tools being required torelease the machine from the base.

Asa further factor in rendering the machine substantially noiseless,when used upon the base of the carrying case, the base may be providedwith a thicklayer of felt v5O on its entire upper surface, the same.preventing transmission of sound.

It will be noted that the two side frames 11 are machine standards topromote the as-' sembly of the parts and establish a machinebase areathat does not include the key-board; that the assembled machine isenclosed by a highly-polished outer frame which also includes a forwardextension to protectively enclose the keyboard of the machine; that theenclosing outer frame is formed with a floorsection of substantially thesame areaas the established base of the machine to enclose the machineon the under side; that the outer crease the base-areaof the machinewhen .in

use and only eoacts with .the cover when the maehineis not in use orbeing carried from place to vplace.

. 'It'will also beseen .thatthe carrying case,beingformedwithasheet-metalbaseeplatefor the typewriting .machine and asheet-metal opposite side wall for the cover, provides a carryingcasehaving aminimum thickness, materially reducing the thickness of carryingcasesin which :the corresponding walls are formed ,of wood or othercompositions.

The arrangement permits the sheet-metal walls to be spaceda minimumdistance apart, with sockets to receive the feet of the typewriter, sothat they will rest directly upon the base. It will be noted that thetypewriting machine with its outer frame resting upon the base-plate,provides a chambered pocket between the'bottom of the outer frame of thetypewriter and the base-plate into which sounds emitted through thebottom of the outer frame are received. This arrangement permits thepositioning of a sound-absorbing padding on the base-plate to furtherdeaden the sounds which enter this chambered pocket. The padding extendsover the base-plate between the sockets for thefeet of -the -machine andthe flanges or frame-members 23 of the base without necessitating anincrease in the space between the two walls.

Variations may be resorted to within the scope of the invention, andportions of they improvements may be used without others.

Having thus described my invention, I claim:

A carrying case for a portable typewriter, comprising a thin, fiat basehaving all its bottom surface in a single plane, a relatively thickseparate strengthening rim attached around the inner. periphery of thebase to form a reinforcement therefor, the base bottom having sockets toreceive the rubber feet of the typewriting machine, sound absorbing feltcovering the interior top of the base bottom and a cover for the caseincluding relatively thick front and rear ends and thinner top and sideportions, said top portion having an inclined front portion, said sidesand top portion being all in a single piece and fastened to saidrelativel thicker ends.
